TYPE DESCRIPTION
NAME LP2950 LP2951
Active-low open-collector error output. Goes low when V
OUT
drops by 6% of its
ERROR — 5 O
nominal value.
Determines the output voltage. Connect to V
TAP
(with OUTPUT tied to SENSE)
FEEDBACK — 7 I to output the fixed voltage corresponding to the part version, or connect to a
resistor divider to adjust the output voltage.
GND 2 4 — Ground
INPUT 3 8 I Supply input
OUTPUT 1 1 O Voltage output.
Senses the output voltage. Connect to OUTPUT (with FEEDBACK tied to V
TAP
)
SENSE — 2 I
to output the voltage corresponding to the part version.
SHUTDOWN — 3 I Active-high input. Shuts down the device.
V
TAP
— 6 O Tie to FEEDBACK to output the fixed voltage corresponding to the part version.
