Drive circuit OUTPUT ON/OFF control circuit ON/OFF Saturation protection Reference voltage Thermal shutdown Over current protection GND ABSOLUTE MAXIMUM RATINGS (TA = 25°C, unless otherwise specified) Parameter Input Voltage Symbol VIN Note Rating Unit 20 V 0.48 W Internal Power Dissipation PT Operating Ambient Temperature TA −30 to +85 °C Operating Junction Temperature TJ −30 to +150 °C Storage Temperature Tstg −55 to +150 °C Thermal Resistance (Junction to Ambient) Rth(J-A) 260 °C/W Note TA ≤ 25°C, internally limited. When the operating junction temperature rises up to 150°C, the internal circuit shuts down the output voltage. Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded. 2 Data Sheet G12905EJ5V0DS µ PC29S00 Series ★ TYPICAL CONNECTION ON/OFF D1 µ PC29S00 INPUT OUTPUT + CIN COUT D2 CIN: 0.1 to 0.47 µF. Be sure to connect to prevent abnormal oscillation. For using capacitors, film capacitors whose voltage and temperature characteristics are excellent are recommended. Take care that some monolithic ceramic capacitor is inferior in the temperature and voltage characteristics. When using the monolithic ceramic capacitor, the CIN needs to be held these capacities in voltage and temperature used. COUT: 10 µF or higher. Be sure to connect to prevent oscillation and to improve the transient load stabilization. Connect the CIN and COUT as close as possible to the IC pins (within 2 cm). D1: Need for VO > VIN D2: Need a shottky barrier diode for VO < GND Cautions 1. When output is off (VON/OFF = low level), the OUTPUT pin should not be supplied higher voltage than VIN voltage from external. 2. Design your circuit and mounting with consideration for heat radiation when using this device.

Caution Apply only one kind of soldering condition to a device, except for "partial heating method", or the device will be damaged by heat stress. Data Sheet G12905EJ5V0DS 9 µ PC29S00 Series CAUTION ON USE When using the µ PC29S00 series at the input voltage which is lower than in the recommended operating condition the big quiescent current flows through device because the transistor of the output paragraph is saturated (Refer to the IBIAS (IBIAS(S)) vs. VIN curves in TYPICAL CHARACTERISTICS). The specification of this characteristics is the start-up quiescent current, IBIAS(S). The µ PC29S00 series has saturation protection circuit, but they sometimes need about 50 mA current. Therefore, the power supply on the input needs the enough current capacity to pass this quiescent current when the device starts up. 10 Data Sheet G12905EJ5V0DS µ PC29S00 Series ★ REFERENCE DOCUMENTS Usage of Three-Terminal Regulators (G12702E) Quality Grades on NEC Semiconductor Devices (C11531E) Semiconductor Device Mounting Technology Manual (C10535E) Review of Quality and Reliability Handbook (C12769E) Semiconductor Selection Guide -Products and Packages- (X13769X) • The information in this document is current as of January, 2003.
