Product Preview

300 mA High Performance

CMOS LDO Regulator with

Enable and Enhanced ESD

Protection

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.

Features

• Output Voltage Options:

Adjustable, 1.3 V, 1.5 V, 1.8 V, 2.8 V, 3.0 V, 3.3 V, 3.5 V, 5.0 V

• Adjustable Output by External Resistors from 5.0 V down to 1.250 V

• Fast Enable Turn-on Time of 15 ms

• Wide Supply Voltage Range Operating Range

• Excellent Line and Load Regulation

• Typical Noise Voltage of 50 mVrms without a Bypass Capacitor

• Enhanced ESD Protection (HBM 3.5 kV, MM 400 V)

• These are Pb-Free Devices

Typical Applications

• SMPS Post-Regulation

• Hand-held Instrumentation & Audio Players

• Noise Sensitive Circuits – VCO, RF Stages, etc.

• Camcorders and Cameras

• Portable Computing
