L4931CZ33-AP L4931 3.3 Volt Very Low Drop Voltage Regulator with Inhibit TO-92



The L4931CZ33-AP is a very low drop regulator in a TO-92 package and a 3.3 Volt output voltage. 

The very low drop voltage (0.4 V) and the very low quiescent current make it particularly suitable for low noise, low power applications and especially in battery-powered systems.

It requires only a 2.2 µF capacitor for stability allowing space and cost saving.
