LP2985-NSNVS018Y –MARCH 2000–REVISED DECEMBER
LP2985-N Micropower 150-mA Low-Noise Ultra-Low-Dropout Regulatorina SOT-23
Package Designed for Use With Very Low ESR Output Capacitors Features Input Voltage Range: 2.5Vto16V Ultra Low-Dropout Voltage Ensured 150 mA Output Current Requires Minimum External Components Stable With Low-ESR Output Capacitor <1 µA Quiescent Current When Shut Down Low Ground Pin CurrentatAll Loads Output Voltage Accuracy 1%(A Grade) High Peak Current Capability Low ZOUT: 0.3Ω Typical (10 Hzto1 MHz) Overtemperature and Overcurrent Protection −40°Cto 125°C Junction Temperature Range Custom Voltages Available
Applications Cellular Phones Palmtop and Laptop Computers Personal Digital Assistants (PDA) Camcorders, Personal Stereos, Cameras
DescriptionThe LP2985-N low noise linear (LDO) regulator
delivers up to 150-mA output current and only
requires 300-mV dropout voltageof inputto output.
Using an optimized vertically integrated PNP (VIP)
process, the LP2985-N delivers unequaled
performance for all battery-powered designs. The
LP2985-N device provides 1% tolerance precision
output voltage with only 75-µA quiescent currentat1- load and 850 µAat 150-mA load. By addinga 10- bypass capacitor, the output noise canbe reduced30 µVRMSina 30-kHz bandwidth.
The LP2985-Nis designedto work witha ceramic
output capacitor with equivalent series resistance
(ESR)as low as5 mΩ. The deviceis available with
fixed output voltage from 2.5Vto 6.1 V. Contact

needs.
