HT75XX-1 100mA Low Power LDO
Features
* Low power consumption * Low voltage drop * Low temperature coefficient * High input voltage (up to 24V) * High output current : 100mA (Pd 250mW) * Output voltage accuracy: tolerance 3% * TO92, SOT89 and SOT23-5 package
Applications
* Battery-powered equipment * Communication equipment * Audio/Video equipment
General Description
The HT75XX-1 series is a set of three-terminal high current low voltage regulator implemented in CMOS technology. They can deliver 100mA output current and allow an input voltage as high as 24V. They are available with several fixed output voltages ranging from 2.1V to 12.0V. CMOS technology ensures low voltage drop and low quiescent current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents.
