NCP603
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, 2.5 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 200 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
