Description
L5150CJ and L5150CS are low dropout linear
regulators with microprocessor control functions
such as power on reset, low voltage reset, early
warning.
Typical quiescent current is 55 μA at very low
output current.
On chip trimming results in high output voltage
accuracy (2%). Accuracy is kept over wide
temperature range, line and load variation. Early
warning circuit monitors the input voltage and
compares it with an internal voltage reference.
Output voltage reset threshold can be adjusted
down to 3.5 V by means of an external voltage
divider.
The maximum input voltage is 40 V. The max
output current is internally limited. Internal
temperature protection disables the voltage
regulator output. In addition, only low-value
ceramic capacitor on output is required for
stability.

Function
Reset adjustable threshold. Connected to an
8
appropriate external voltage divider, it allows to
properly set the reset threshold down to 3.5 V.
Connect to GND if not needed.
Reset output. Internally connected to Vo through a
1 20 Kpull up resistor. This pin is pulled low when
Vo < Vo_th. Keep open if not needed.
Reset delay. Connect an external capacitor between
2 Vcr pin and ground to adjust the reset delay time.
Keep open if not needed.
3 Ground reference.
- Not connected.
4
5 V regulated output. Block to GND with a ceramic
capacitor (Co 220 nF for regulator stability).
5
Supply voltage, block directly to GND on the IC with a
capacitor.
Early warning input. This pin monitors the VS voltage
6 level through a resistor divider. Connect to VS if not
needed.
Early warning output. Internally connected to Vo
7
through 20 Kpull up resistor. This pin is pulled low
when EWi is below bandgap reference voltage. Keep
open if not needed.
TAB is connected to the substrate of the chip: connect
- toGND or leave open (see Figure 2 for PowerSSO-12
only).
