HT1015-1 -- 1.5V Low Power LDO

HT1015-1
1.5V Low Power LDO
Features
· Low power consumption
· Wide operating voltage (12V max.)
· Low voltage drop
· TO92, SOT89 and SOT23-5 package
· Low temperature coefficient
Applications
· Battery-powered equipment
· Audio/Video equipment
· Communication equipment
General Description
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.
Although designed primarily as a fixed voltage regulator,
this device can be used with external components to obtain variable voltages and currents.
