| HT75XX-1 100mA Low Power LDO Features * Low power consumption * Low voltage drop * Low temperature coefficient * High input voltage (up to 24V) * High output current : 100mA (Pd 250mW) * Output voltage accuracy: tolerance 3% * TO-92, SOT-89 and SOT-25 package Applications * Battery-powered equipment * Communication equipment * Audio/Video equipment General Description The HT75XX-1 series is a set of three-terminal high current low 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 3.0V to 5.0V. CMOS technology ensures low voltage drop and low quiescent current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. Selection Table Part No. HT7530-1 HT7533-1 HT7536-1 HT7544-1 HT7550-1 Note: XX stands for output voltages. For lead free devices, TO-92 package will add a # mark at the end of the date code, whereas SOT-89 & SOT-25 packages will add a # mark at the end of the marking.
