DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT PC2900 Series THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR The PC2900 series of low dropout voltage three terminal positive regulators is constructed with PNP output transistor. The PC2900 series feature the ability to source 1 A of output current with a low dropout voltage of typically 0.7 V. The power dissipation of the PC2900 series can be drastically reduced compared with the conventional three terminal positive voltage regulators that is constructed with NPN output transistor. Also, this series corresponds to the low voltage output (3 V, 3.3 V) which is not in the conventional low dropout regulators (PC2400A series). FEATURES * Output current in excess of 1.0 A * Low dropout voltage VDIF = 0.7 V TYP. (at IO = 1 A) * On-chip overcurrent and thermal protection circuit * On-chip output transistor safe area protection circuit PIN CONFIGURATION (Marking Side) PC2900HF Series: MP-45G PC2900HB Series: MP-3 PC2900T Series: MP-3Z 4 1 2 3 1 2 1: INPUT 2: GND 3: OUTPUT 3 1: 2: 3: 4: INPUT GND OUTPUT GND (Fin) The information in this document is subject to change without notice.

If other soldering processes are used, or if the soldering is perfomed under different condition, please make sure to consult with our sales offices. Fof more details, refer to our document "SEMICONDUCTOR DEVICE MOUNTING TECHNOLOGY MANUAL" (C10535E). Surface mount devices PC2900T Series: MP-3Z Process Conditions Symbol Infrared ray reflow Peak temperature: 235 C or below (Package surface temperature), Reflow time: 30 seconds or less (at 210 C or higher), Maximum number of reflow processes: 2 times. IR35-00-2 VPS Peak temperature: 215 C or below (Package surface temperature), Reflow time: 40 seconds or less (at 200 C or higher), Maximum number of reflow processes: 2 times. VP15-00-2 Wave soldering Solder temperature: 260 C or below, Flow time: 10 seconds or less, Maximum number of flow processes: 1 time, Pre-heating temperature: 120 C or below (Package surface temperature). WS60-00-1 Partial heating method Pin temperature: 300 C or below, -- Heat time: 3 seconds or less (Per each side of the 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. Through-hole devices PC2900HF Series: MP-45G PC2900HB Series: MP-3 Process Wave soldering (only to leads) Partial heating method Conditions Solder temperature: 260 C or below, Flow time: 10 seconds or less. Pin temperature: 300 C or below, Heat time: 3 seconds or less (Per each pin). Caution For through-hole device, the wave soldering process must be applied only to leads, and make sure that the package body does not get jet soldered. 17 PC2900 Series CAUTION ON USE When using the PC2900 series at the input voltage which is lower than in the recommended operating condition, the big quiescent current flows through devices because the transistor of the output paragraph is saturated (Refer to IBIAS (IBIAS (s)) vs VIN curves in TYPICAL CHARACTERISTICS). The PC2900 series have saturation protection circuits, but they sometimes need about 80 mA current. Therefore the power supply on the input needs the enough current capacity to pass this quiescent current when the devices startup.

NEC Corporation assumes no responsibility for any errors which may appear in this document. NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product. M4 96.5 20
