FAST-TRANSIENT-RESPONSE 1-A LOW-DROPOUT VOLTAGE REGULATORS
FEATURES
• 1 A Low-Dropout Voltage Regulator
• Available in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V,
3.0-V, 3.3-V, 5.0-V Fixed Output and
Adjustable Versions
• Dropout Voltage Down to 230 mV at 1 A
(TPS76850)
• Ultralow 85 µA Typical Quiescent Current
• Fast Transient Response
• 2% Tolerance Over Specified Conditions for
Fixed-Output Versions
• Open Drain Power Good (See TPS767xx for
Power-On Reset With 200-ms Delay Option)
• 8-Pin SOIC and 20-Pin TSSOP (PWP) Package
• Thermal Shutdown Protection
DESCRIPTION
This device is designed to have a fast transient
response and be stable with 10µF low ESR capaci-
tors. This combination provides high performance at a
reasonable cost.
