1 / 10 page HI-SINCERITY MICROELECTRONICS CORP. Spec. No. : IC200403 Issued Date : 2004.03.01 Revised Date : 2004.08.31 Page No. : 1/10 H78LXXAM / BM, H78LXXAA / BA HSMC Product Specification H78LXXAM / BM H78LXXAA / BA 3-TERMINAL POSITIVE VOLTAGE REGULATORS Description These regulators employ internal current-limiting and thermal-shutdown, making them essentially indestructible. They can deliver up to 100mA output current. Features • Maximum Output Current of 100mA (Tc=25°C) • Internal Short-Circuit Current Limiting • Internal Thermal Overload Protection • TO-92 & SOT-89 Package Absolute Maximum Ratings (Ta=25 °C, Unles Otherwise Specified) Characteristic Symbol Rating Unit Input Voltage V IN 40 V TO-92 700 mW Power Dissipation P D SOT-89 500 mW Operating Temperature T opr -30 to 85 oC Storage Temperature T stg -55 to 150 oC Junction Temperature T j 150 oC Thermal Resistance R th(j-a) 208 oC/W Schematic Diagram & Equivalent Circuit H78LXX Series Pin Assignment Typical Application Schematic Diagram Equivalent Circuit VOUT VIN 3-Lead Plastic TO-92 Package Code: A Pin 1: VOUT Pin 2: GND Pin 3: VIN 1 2 3 3-Lead Plastic SOT-89 Package Code: M Pin 1: VOUT Pin 2: GND Pin 3: VIN 1 2 3 Note 1: C IN is required if regulator is located an appreciable distance from power supply filter. Note 2: C OUT is not needed for stability; however, it does improve transient response. Values of less than 0.1uF could cause instability. 1 3 2 H78LXX Series VOUT VIN CIN 0.33uF (Note 1) COUT 0.1uF (Note 2) 3 1 2 Starting Circuit Reference Voltage Current Generator Error Amplifier SOA Protection Thermal Protection Series Pass Element Output GND Input |
