PAM3108
MAXIMUM 1.5A, ULTRA LOW DROPOUT REGULATOR
Description
The PAM3108 is a high performance positive voltage regulator
designed for use in applications requiring very low Input voltage and
very low dropout voltage at up to 1.5A. It operates with a VIN as low
as 1.1V and VDD voltage 3V with output voltage programmable as low
as 0.8V. The significant feature includes ultra low dropout, ideal for
applications where VOUT is very close to VIN. Additionally, there is an
enable pin to further reduce power dissipation while shutdown. The
PAM3108 provides excellent regulation over variations in line, load,
temperature and provides a power OK signal to indicate if the voltage
level of Vo reaches 90% of its rating value.
The PAM3108 is available with SOP-8 (Exposed Pad) and WDFN-
10L 3x3 packages.
