PC29xxB Series
THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR
(OUTPUT CURRENT: 1.0 A)
DESCRIPTION
The
μ
PC29xxB series is a series of three-terminal low dropout voltage regulators with 1.0 A output current. This
series is suitable for low voltage operated IC and has 4 output voltage types, 1.8 V, 2.5 V, 3.3 V and 5.0 V. Compared
with the
μ
PC29xx and
μ
PC29xxA series, this series has improved output voltage tolerance (V
O
±
2%), quiescent
current (1.8 mA TYP. (I
O
= 0 A)), and short-circuit current.

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

If using a laminated ceramic capacitor, it is
necessary to ensure that C

: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode.
: If the OUTPUT pin has a lower voltage than the GND pin, connect a Schottky barrier diode.
Caution Make sure that no voltage is applied to the OUTPUT pin from external.
