LINEAR INTEGRATED CIRCUIT

LOW DROPOUT LINEAR

REGULATOR CONTROLLER



DESCRIPTION

The UTC LC1111 is a low dropout linear regulator controller for

applications requiring high-current and ultra low dropout voltages.

The use of an external N-Channel MOSFET and provide an

adjustable output by using an external resistive divider.

An extremely accurate 0.8V (±2%) reference allows the

implementation of sub 1 V voltage supplies. The reference is

guaranteed over the complete supply and temperature ranges.

The UTC LC1111 integrates various functions. For example, a

Power-On-Reset (POR) circuit monitors V_CCsupply voltage to

prevent wrong operations; the function of Under-Voltage

Protection (UVP) protects the device from short circuit condition.

The soft-start of output voltage is adjustable by the external

capacitor on SS pin. Moreover, the UTC LC1111 can be enabled

by other power system; namely, holding the EN above 1.6V

enables output and pulling the EN under 0.4 disables output.
