HT7333 Datasheet



The HT73XX series is a set of three-terminal, low power,high voltage regulators implemented in CMOS technology.The series features extremely low quiescent currentwhich is typically 4A. They allow input voltages ashigh as 12V. The device provides large current with asignificantly small dropout voltage.The HT73XX consists of a high-precision voltage reference,an error correction circuit, and a current limitedoutput driver. They are available with several fixed outputvoltages ranging from 1.8V to 5.0V. CMOS technologyensures low dropout voltage and low currentconsumption. Although designed primarily as fixed voltageregulators, these devices can be used with externalcomponents to generate variable voltages and currents. HT7333 Features • Ultra low quiescent current: 4A (typ.)• High input voltage (up to 12V)• Output voltage:1.8V, 2.5V, 2.7V, 3.0V, 3.3V, 3.5V, 5.0V• Output voltage accuracy: tolerance 3%• Maximum output current: 250mA• Low dropout voltage• Low temperature coefficient• TO-92, SOT-89 package HT7333 Applications • Battery-powered equipment• Voltage regulator for microprocessor• Voltage regulator for LAN cards• Wireless Communication equipment• Audio/Video equipment
