Maximum output current: 250mA High input voltage (up to 12V) Low dropout voltage Output voltage: Low temperature coefficient 1.8V, 2.5V, 2.7V, 3.0V, 3.3V, 3.5V, 5.0V TO-92, SOT-89 package Output voltage accuracy: tolerance 3% Applications Battery-powered equipment Wireless Communication equipment Voltage regulator for microprocessor Audio/Video equipment Voltage regulator for LAN cards General Description The HT73XX series is a set of three-terminal, low power, The HT73XX consists of a high-precision voltage refer- high voltage regulators implemented in CMOS technol- ence, an error correction circuit, and a current limited ogy. The series features extremely low quiescent cur- output driver. They are available with several fixed out- rent which is typically 3.5A . They allow input voltages put voltages ranging from 1.8V to 5.0V. CMOS technol- as high as 12V. The device provides large current with a ogy ensures low dropout voltage and low current significantly small dropout voltage. consumption. Although designed primarily as fixed volt- age regulators, these devices can be used with external components to generate variable voltages and currents.
