OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.

Enable Pin. Drive EN high to turn on the regulator. Drive EN low to turn off the regulator.
Reference-Noise Bypass Pin (fixed voltage version only). Bypass with an external capacitor
CBP can reduce output noise to very low level.
Feedback Voltage Input Pin (adjustable voltage version only). Connect this pin to the
external resistor divider to adjust the output voltage.
Regulator Output Pin. It is recommended to use 1μF or larger ceramic output capacitor from
OUT pin to ground. The capacitor should be located very close to this pin.

NOTES:
1. The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V (only
applicable for VOUT = +2.5V to +5.0V).
2. VEN = -0.3V to VIN.
3. Time needed for VOUT to reach 90% of final value.
