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