Holtek HT1015-1 1.5v low power ldo Datasheet

HT1015-1
1.5V Low Power LDO
Features
· Low power consumption
· Wide operating voltage (12V max.)
· Low voltage drop
· TO-92, SOT-89 and SOT-25 package
· Low temperature coefficient
Applications
· Battery-powered equipment
· Audio/Video equipment
· Communication equipment
General Description
Although designed primarily as a fixed voltage regulator,
this device can be used with external components to obtain variable voltages and currents.
The HT1015-1 is a three-terminal low power voltage regulator implemented in CMOS technology. It is available with
a fixed output voltage at 1.5V. CMOS technology ensures
low voltage drop and low quiescent current.
