  1997 data sheet bipolar analog integrated circuit m pc29m00 series three terminal low dropout voltage regulator the m pc29m00 series of low dropout voltage three terminal positive regulators is constructed with pnp output transistor. the m pc29m00 series feature the ability to source 0.5 a of output current with a low dropout voltage of typically 0.5 v. the power dissipation of the m pc29m00 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 ( m pc24m00a series). features ? output current in excess of 0.5 a ? low dropout voltage v dif = 0.5 v typ.

m pc29m00 series 17 recommended soldering conditions when soldering this product, it is highly recommended to observe the conditions as shown below. 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 m pc29m00t series: mp-3z process conditions symbol infrared ray reflow peak temperature: 235 c or below (package surface temperature), ir35-00-2 reflow time: 30 seconds or less (at 210 c or higher), maximum number of reflow processes: 2 times. vps peak temperature: 215 c or below (package surface temperature), vp15-00-2 reflow time: 40 seconds or less (at 200 c or higher), maximum number of reflow processes: 2 times. wave soldering solder temperature: 260 c or below, flow time: 10 seconds or less, ws60-00-1 maximum number of flow processes: 1 time, pre-heating temperature: 120 c or below (package surface temperature). 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 m pc29m00hf series: mp-45g m pc29m00hb series: mp-3 process conditions wave soldering solder temperature: 260 c or below, (only to leads) flow time: 10 seconds or less. partial heating method 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.
m pc29m00 series 18 caution on use when using the m pc29m00 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 i bias (i bias (s) ) vs v in curves in typical characteristics ). the m pc29m00 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. reference documents quality grade on nec semiconductor devices c11531e semiconductor device mounting technology manual c10535e ic package manual c10943x guide to quality assuarance for semiconductor devices mei-1202 semiconductors selection guide x10679e nec semiconductor device reliability/quality control iei-1212 system-three terminal regulator
