HT7430 3.0V Negative Voltage Regulator Features · Low power consumption · High input voltage (up to -24V) · Low voltage drop · High output current : 100mA (Pd £ 250mW) · Low temperature coefficient · TO-92 and SOT-89 package Applications · Battery-powered equipment · Audio/Video equipment · Communication equipment General Description The HT7430 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. 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.
