NCP156ABFCT120280T2G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The NCP156ABFCT120280T2G is a dual-output low dropout linear regulator optimized for camera modules. It provides a high-current bias rail (OUT1) and a precise analog sensor supply (OUT2). OUT1 delivers 500 mA at a fixed 1.2 V output, while OUT2 supplies 250 mA at a fixed 2.8 V output. The device features ultra-low dropout voltages of 70 mV and 95 mV respectively. It includes active output discharge and normal slew rate settings.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function of the EN pin?

The EN pin enables both voltage outputs when the voltage reaches 0.9 V. An internal pull-down ensures the device remains off if the pin is unconnected.

How does the NCP156 handle overcurrent conditions?

Each output channel has independent current limit protection. If the output voltage drops to 90% of nominal, the current is limited to typical values of 850 mA for OUT1 and 550 mA for OUT2.
