A6015
REGULATOR CMOS LOW DROPOUT REGULATOR (LDO)
MAXIMUM 1.5A, ULTRA LOW DROPOUT REGULATOR
DESCRIPTION
FEATURES
The A6015 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 A6015 provides excellent regulation over
variations in line, load and temperature. And
provides a power OK signal to indicate if the
voltage level of VOUT reaches 90% of its rating
value.
Maximum 1.5A Low-Dropout Voltage Regulator
High Accuracy Output Voltage ±1.5%
Typically 150mV Dropout at 1.5A
