OTHER LDO REGULATORS
The SGS-Thomson L4940V5 LDO can also be used to post
regulate the 5V
OUT
DCP010505 and can deliver a regulated
minimum 4.75V up to 135mA.
The 5V
OUT
DCP010505 can also be post regulated with the
Micrel MIC5207 which offers up to 180mA output drive
with a typical dropout voltage of 165mV at 150mA. The
MIC5207 is available in a micro-sized SOT23-5 package
which gives the minimum additional board area for post
regulation.

2. To predict the output voltage at 10% load take the mea-
sured or specified voltage at 75% load and multiply by
(1 + Load Reg 10% to 75%). For example a DCP010505P
typical V
OUT
at 10% load will be 5V
x
(1 + 17%) = 5.85V.
3. To predict the output voltage at 25% load on higher V
OUT
versions take the measured or specified voltage at 75%
load and multiply by (1 + Load Reg 25% to 75%). For
example a DCP010512P typical V
OUT
at 25% load will be
12V
x
(1 + 12%) = 13.4V. To then estimate the voltage at
10% load take the previously calculated V
OUT
at
25% load and multiply by (1 + Load Reg 10% to 25%).
In this case the typical V
OUT
at 10% load will be 13.4V
x
(1 + 7%) = 14.3V.
To obtain predictions for loads other than those specified
assume the V
OUT
versus load characteristic is linear between
the load points and calculate accordingly. The 10% to 100%
load specification guarantees the maximum voltage excursion
for any load between 10% to 100% with respect to V
OUT
at
75% load.
The above does not take into consideration line regulation and
assumes a nominal input voltage. The 1:1 line regulation of the
DCP01 family means that a percentage change in the input
will give a corresponding percentage change in the output.
1. To predict the output voltage at 100% load take the mea-
sured or specified voltage at 75% load and multiply by
(1 + Load Reg 75% to 100%). For example a DCP010505P
typical V
OUT
at 100% load will be 5V
x
(1 – 8%) = 4.6V.
