http://onsemi.com
The NCP603 provides 300 mA of output current at fixed voltage
options, or an adjustable output voltage from 5.0 V down to 1.250 V. It
is designed for portable battery powered applications and offers high
performance features such as low power operation, fast enable
response time, and low dropout.
The device is designed to be used with low cost ceramic capacitors
and is packaged in the TSOP-5/SOT23-5.
