General Description
The GS7137 is a CMOS linear regulator
optimized for fast transient response. It
guarantees delivery of 300mA output current. The
device is available in fixed output voltage from
1.2V to 4.0V.
Based on its low quiescent current consumption
and its less than 1uA shutdown mode, the
GS7137 is ideal for battery- powered applications.
The line transient response and load transient
response of the GS7137 are excellent, thus the
device is suitable for the power supply for
handheld communication equipment. The
regulator is stable with small ceramic capacitive
loads (2.2µF typical).
Applications
Portable communication equipment
Notebook Computer
Battery Powered Systems
