LINEAR INTEGRATED CIRCUIT
400mA LOW-DROP VOLTAGE
REGULATOR
DESCRIPTION
The UTC UCV676/A is a low dropout voltage regulator with a
400mA output current used in harsh automotive environments. It
can be used in wide input voltage and operating temperature
ranges.
It has a high peak input voltage tolerance and reverse input
voltage protection. Built-in heat protection circuit, current limiting
circuit and inhibit control circuit. The UTC UCV676/A family is
available in TO-263-5 and TO-252-4 surface mount packages.
The output is stable over a wide output capacitance and ESR
range.
FEATURES
* 2.5V and 1.8V ±4% Output Voltage
* 3.3V, 5.0V, and Adjustable Voltage Version (from 2.5V~20V)
±4% or ±2% Output Voltage
* 400mA Output Current
* 500mV (max) Dropout Voltage (5.0V Output)
* Inhibit control input
* Very Low Current Consumption
* Fault Protection
- +45V Peak Transient Voltage
- Overcurrent
- Overheat

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. During the voltage range which exceeds the maximum tested voltage of VIN, operation is assured, but not
specified. Wider limits may apply. Thermal dissipation must be observed closely.
