HT7321-2

HT73xx-2 30V, 250mA TinyPowerTM LDO Features Low power consumption Low voltage drop Low temperature coefficient High input voltage - up to 30V Output voltage accuracy: tolerance ±1% Over current protection TO-92, SOT89-3, and 8-pin SOP-EP packages Applications Battery-powered equipment Communication equipment Audio/Video equipment General Description The HT73xx-2 device series are low power high voltage regulators implemented in CMOS technology which have the advantages of low voltage drop and low quiescent current. They allow input voltages as high as 30V. They are available with several fixed output voltages ranging from 2.1V to 5.0V. The softstart function inhibits the problem of output overshoot during power on. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents.
