There are plenty of applications where both positive and negative power supplies are simultaneously required. Examples include audio amplifiers, sensors, Operational Amplifiers, ADCs, DACs, LCDs, and more. There are many ways to “split” a single supply to behave like a dual supply.
The remarkable property of a dual-rail supply is that compared to the positive DC voltages, whose voltage is positive concerning GND potential, this supply can also provide negative voltage. DC supplies are more commonly used in everyday electronics than AC supplies.
As well as connecting individual batteries together in series, parallel of combinations of both, in order to create one single voltage supply, we can also connect batteries together to create what are commonly called Dual-voltage power supplies or Dual-polarity power supplies.
One way to get positive and negative voltage is by using a centre-tap transformer. A so-called “12-0-12 transformer” is an example of a centre-tapped transformer. The primary terminals of this centre-tapped transformer are connected to the main supply (220VAC, 50Hz), with the output coming from the secondary terminals.
Making a bidirectional positive supply is straightforward as there are many available integrated circuits (ICs) that can source and sink current. The problem is that the negative supply needs to source and sink current as well, as required by the device under test (DUT).
The dual-output voltage rail is developed to reduce the number of bidirectional supplies needed to one, while still providing positive and negative bidirectional capable sources for the DPS. Making a bidirectional positive supply is straightforward as there are many available integrated circuits (ICs) that can source and sink current.

So you can create 5V from this battery by using a boost converter. Another option is to use two buck converters, one for 2.5V and another one for - 2.5V. If you need extremely silent rails- LDO to 2.5V, buck to - 4V or so, and a negative LDO. Those LDOs come as complimentary positive and negative regulators, for RF applications.
1. Series Battery Method. One of the simplest ways to create a dual power supply is by using two sets of batteries. The batteries are connected in series, so that the positive terminal of one battery is attached to the negative terminal of the second battery. When this middle connection is used as the ground reference for the circuit, you will ...
Because batteries have a positive and negative terminal, they are ideal for use in dual balanced power supplies. Dual-voltage power supplies typically have a positive and negative power source that is equal in voltage value but opposite in polarity, in addition to a zero ground point midway between the two voltages.

Let''s build a cheap adjustable dual power supply circuit that uses a 7805 and a 7905 linear regulator IC as the main components. This circuit is also a great way to understand the basics of OP-AMP circuits. It can supply a voltage ranging from +5V to +25V and -5V to -25V, which means that it can supply both positive and negative power. Both ...
The objective of this project is to convert 220V AC supply in to +12V and -12v DC supply, that is why it is named Dual Power Supply as we get positive and negative 12v power supply at the same time. This can be achieved in simple three steps: Firstly, 220V AC is converted into 12V AC by using simple step-down (220V/12V) transformer.
It is possible to design a dual power supply using a positive and negative three terminal IC regulator. This is referred as split power supply.

The output capacitors improve the transient ...
For the positive supply, you need a boost converter. This is assuming you connect the negative side of your 3.7 V battery to ground. There are also switcher chips that are intended for making a negative supply from a positive one. If your negative current demand is low enough, a charge pump might be all you need.
