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_CC supply 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.
