HI-SINCERITY MICROELECTRONICS CORP. Spec. No. : Preliminary Data Issued Date : 2001.01.01 Revised Date : 2001.05.21 Page No. : 1/3 H78M05AT H78M05BT 3-TERMINAL POSITIVE VOLTAGE REGULATOR Description The H78M05_T series of three-terminal positive regulators are available in the TO-126 package. This regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each device employs internal current limiting, thermal shut-down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 0.5A output current. Although designed primarily as fixed voltage regulators, this device can be used with external components to obtain adjustable voltages and currents. Description • Output current up to 500mA is available. • Eliminates external compensating circuit. • Built-in current limiter prevents elements from destruction when load is short circuit. • Built-in chip junction temperature limiting circuit protects elements against thermal destruction. • Built-in internal power dissipation limiting circuit protects transistors at output driver. Absolute Maximum Ratings (Ta=25°C) • Input Voltage ................................................................................................................................... 35 V • Total Power Dissipation (Tc=25°C) ................................................................................ Internally limited • Operating Junction Temperature ...................................................................................... 0 °C to 125 °C • Output Current (Tc=25°C) .............................................................................................................. 0.5 A • Lead Temperature (Soldering 10S) .............................................................................................. 230 °C Typical Application Block Diagram Vin 1 H78M05_T 2 3 Vout 1 Input Current Generator Series pass Element SOA Protection Error Amplifier Thermal Protection 3 Output C1 C2 Starting Circuit Reference Voltage Note : C1 and C2 are required if regulator is located far from power supply filter and load, or oscillation may induced on the loop. 2 GND H78M05AT, H78M05BT HSMC Product Specification HI-SINCERITY MICROELECTRONICS CORP.
