• Stable with Low-ESR Output Capacitor
• Low Ground Pin Current at All Loads
• Output Voltage Accuracy 1% (A Grade)
• High Peak Current Capability
• Wide Supply Voltage Range (16 V Maximum)
• Overtemperature and Overcurrent Protection
40°C to +125°C Junction Temperature Range
• Requires Minimum External Components
2 Applications
• Cellular Phones
• Palmtop/Laptop Computers
• Personal Digital Assistants (PDA)
• Camcorders, Personal Stereos, Cameras
3 Description
The LP2983 is a 150-mA, fixed-output voltage
regulator designed to provide tight voltage regulation
in applications with output voltages 1.2 V.
Using an optimized vertically integrated PNP (VIP)
process, the LP2983 delivers unequaled performance
in all critical specifications:
• Ground pin current: Typically 825 µA at a 150-mA
load, and 75 µA at a 1-mA load.
• Enhanced stability: The LP2983 is stable with
output capacitor ESR down to zero, which allows
the use of ceramic capacitors on the output.
• Precision output: 1% tolerance output voltages
available (A grade).
• Smallest possible size: SOT-23 package uses
absolute minimum board space.
