μPC79Lxx Series
THREE TERMINAL NEGATIVE VOLTAGE REGULATOR
<R> DESCRIPTION
The μ PC79Lxx Series are three-terminal negative output voltage stabilization power supply circuit of fixed output
voltage. It regulates non-stabilized DC input voltage to output stabilized fixed voltage.
The four types of voltage value are 5 V, 8 V, 12 V, and 15 V, and they can be respectively used as power supply
circuit with maximum current capacity 100 mA.
<R> FEATURES
Output current : 100 mA
On-chip some protection circuits
(over current protection, thermal shut down)
Low noise : 31 μV r.m.s. (μ PC79L05)
High ripple rejection : 85 dB (μ PC79L05)
TO-92 package

<R> 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.
<R> TYPICAL CONNECTION
CIN : Required if regulator is located an appreciable distance from power supply filter (More than 2.2 μ F).
COUT: Connect it within 2 cm from OUTPUT pin and GND pin (More than 1 μ F).
D1 : Needed for VIN > VO.
D2 : Needed for VO > GND.
