HT72XX General Purpose Regulator Features * * * High input voltage (up to 24V) Low power consumption High output current : 100mA (Pd 250mW) * * * Low voltage dropout Low temperature coefficient TO-92 package * Audio/Video equipment Applications * * Battery-Powered equipment Communication equipment General Description The HT72XX series is a set of three-terminal high current high voltage regulator implemented in CMOS technology. They can deliver 100mA output current and allow an input voltage as high as 24V. They are available with several fixed output voltages ranging from 2.4V to 15V. The advantages of CMOS technology give low voltage dropout and low quiescent current. Block Diagram Pin Assignment Although designed primarily as fixed voltage regulator, these devices can be used with external components to obtain variable voltages and currents. 1 14th Jan '98 HT72XX Selection Guide Item Pin Assignment Output Voltage Tolerance HT7230 HT7231 B A 3.0V 2.4%, 5% HT7233 HT7234 B A 3.3V 2.4%, 5% HT7245 HT7246 B A 4.5V 2.4%, 5% HT7250 HT7251 B A 5.0V 2.4%, 5% HT7260 HT7261 B A 6.0V 2.4%, 5% HT7270 HT7271 B A 7.0V 2.4%, 5% HT7280 HT7281 B A 8.0V 2.4%, 5% HT7290 HT7291 B A 9.0V 2.4%, 5% HT72C0 HT72C1 B A 12V 2.4%, 5% Note: Selectable regulation voltage range from 2.4V to 9V in 0.1V increments.
