ADP3309


Overview
FEATURES ±1.
2% accuracy over line and load regulations @ 25°C Ultralow dropout voltage: 120 mV typical @ 100 mA Requires only COUT = 0.
47 μF for stability anyCAP LDOs are stable with all types of capacitors (including MLCC) Current and thermal limiting Low noise Low shutdown current: 1 μA 2.
8 V to 12 V supply range −20°C to +85°C ambient temperature range Several fixed voltage options Ultrasmall 5-lead SOT-23 package Excellent line and load regulations APPLICATIONS Cellular telephones Notebook, palmtop computers Battery-powered systems PCMCIA regulator Bar code scanners Camcorders, cameras GENERAL DESCRIPTION The ADP3309 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators.
It is pin-for-pin and functionally compatible with National’s LP2981, but offers performance advantages.
The ADP3309 stands out from conventional LDOs with a novel architecture and an enhanced process.
Its patented design requires only a 0.
