HT7540-1

HT75xx-1 100mA TinyPowerTM LDO Features General Description • Low power consumption The HT75xx-1 series is a set of three-terminal low power high voltage implemented in CMOS technology. They can deliver 100mA output current and allow an input voltage as high as 30V. They are available with several fixed output voltages ranging from 2.1V to 12.0V. CMOS technology ensures low voltage drop and low quiescent current. • Low voltage drop • Low temperature coefficient • High input voltage (up to 30V) • Quiescent current 2.5μA • High output current : 100mA Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. • Output voltage accuracy: tolerance ±3% • 3-pin TO92, 3-pin SOT89 and 5-pin SOT23 packages Applications • Battery-powered equipment • Communication equipment • Audio/Video equipment Selection Table Part No. Output Voltage HT7521-1 2.1V HT7523-1 2.3V HT7525-1 2.5V HT7527-1 2.7V HT7530-1 3.0V HT7533-1 3.3V HT7536-1 3.6V HT7540-1 4.0V HT7544-1 4.4V HT7550-1 5.0V HT7560-1 6.0V HT7570-1 7.0V HT7580-1 8.0V HT7590-1 9.0V HT75A0-1 10.0V HT75C0-1 12.0V Package Marking TO92 SOT89 SOT23-5 75xx-1 (for TO92) 75xx-1 (for SOT89) 5xx1 (for SOT23-5) Note: ″xx″ stands for output voltages.
