HT7150-3

HT71xx-3 30mA TinyPowerTM LDO Features General Description • Low power consumption The HT71xx-3 series is a set of three-terminal low power high voltage regulators implemented in CMOS technology. They allow input voltages as high as 30V. They are available with several fixed output voltages ranging from 2.1V to 5.0V. CMOS technology ensures low voltage drop and low quiescent current. • Low voltage drop • Low temperature coefficient • Quiescent current 1μA • High input voltage (up to 30V) • Output voltage accuracy: tolerance ±2% Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. • TO92, SOT89 and SOT23-5 package Applications • Battery-powered equipment • Communication equipment • Audio/Video equipment Selection Table Part No. Output Voltage HT7121-3 2.1V HT7123-3 2.3V HT7125-3 2.5V HT7127-3 2.7V HT7130-3 3.0V HT7133-3 3.3V HT7136-3 3.6V HT7144-3 4.4V HT7150-3 5.0V Package Marking TO92 SOT89 SOT23-5 71xx-3 (for TO92) 71xx-3 (for SOT89) 1xx3 (for SOT23-5) Note: ″xx″ stands for output voltages.
