PC29Mxx Series
THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR
The
µ
PC29Mxx series of low dropout voltage three terminal positive regulators is constructed with PNP output
transistor. The
µ
PC29Mxx 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
µ
PC29Mxx 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 (3.0 V, 3.3 V) which is not in the conventional low dropout regulators (
µ
PC24MxxA series).
FEATURES
• Output current in excess of 0.5 A
• Low dropout voltage
V
DIF
= 0.5 V TYP. (I

= 0.5 A)
• On-chip over-current and thermal protection circuit
• On-chip output transistor safe operating area protection circuit

Note
Internally limited. When the operating junction temperature rises above 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.

to prevent parasitic oscillation. Set this value according to the
length of the line between the regulator and the INPUT pin. Use of a film capacitor or other capacitor
with first-rate voltage and temperature characteristics is recommended. If using a laminated ceramic
