HT7350-A

HT73xx Series Low Power Consumption LDO Features General Description • Ultra low quiescent current: 3.5µA (typ.) The HT73XX series is a set of three-terminal, low power, high voltage regulators implemented in CMOS technology. The series features extremely low quiescent current which is typically 3.5µA . They allow input voltages as high as 12V. The device provides large current with a significantly small dropout voltage. • High input voltage (up to 12V) • Output voltage: 1.8V, 2.5V, 2.7V, 3.0V, 3.3V, 3.5V, 4.15V, 5.0V • Output voltage accuracy: tolerance ±3% • Maximum output current: 250mA • Low dropout voltage The HT73XX consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. They are available with several fixed output voltages ranging from 1.8V to 5.0V. CMOS technology ensures low dropout voltage and low current consumption. Although designed primarily as fixed voltage regulators, these devices can be used with external components to generate variable voltages and currents. • Low temperature coefficient • 3-pin TO92, 3-pin SOT89 package Applications • Battery-powered equipment • Voltage regulator for microprocessor • Voltage regulator for LAN cards • Wireless Communication equipment • Audio/Video equipment Selection Table Part No. Output Voltage HT7318 1.8V HT7325 2.5V HT7327 2.7V HT7330 3.0V HT7333 3.3V HT7335 3.5V HT7341 4.15V HT7350 5.0V Package Marking SOT89 TO92 73xx-A (for SOT89) 73xx-A (for TO92) Note: ″xx″ stands for output voltages.
