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 SOT89 package Applications …
