NCP1117STAT3G Product Overview

The NCP1117STAT3G is a low dropout (LDO) positive linear voltage regulator from onsemi's NCP1117 series, housed in a SOT-223 surface-mount package. It delivers output current in excess of 1.0A with a maximum dropout voltage of only 1.2V at 800mA, operates from input voltages up to 20V, and features an adjustable output voltage programmable from 1.25V to 18.8V using two external resistors. On-chip trimming adjusts the reference/output voltage to ±1.0% accuracy, and internal protection features include output current limiting, safe operating area compensation, and thermal shutdown. The NCP1117STAT3G is a pin-compatible replacement for the LM1117 and is widely used in consumer electronics, industrial control, automotive electronics, communication equipment, and battery chargers.

FAQ

Q: How is the output voltage set?
A: The NCP1117STAT3G is the adjustable version, with output voltage set by two external resistors from 1.25V to 18.8V. The formula is: VOUT = 1.25 × (1 + R2/R1), where R1 is the resistor from ADJ pin to ground and R2 is from output to ADJ pin. R1 is typically selected as 120Ω to 240Ω to set approximately 5mA current through the ADJ pin.

Q: What is the dropout voltage?
A: The maximum dropout voltage is 1.2V at 800mA output current over the full temperature range.

Q: What protection features are integrated?
A: Internal protection features include output current limiting, safe operating area compensation, and thermal shutdown to protect the device and system under abnormal conditions.

Q: What is the PSRR?
A: 73dB at 120Hz, effectively suppressing input supply ripple effects on the output voltage.

Q: What are the input and output capacitor requirements?
A: A minimum 1μF ceramic capacitor (X7R or X5R type) is recommended at the input, placed as close to the IC as possible. A minimum 10μF ceramic capacitor is recommended at the output; if tantalum or aluminum electrolytic capacitors are used, the capacitance should be greater than 22μF with sufficiently low ESR to avoid instability or oscillation.

Q: What should be noted for thermal design?
A: The NCP1117 generates heat at higher load currents. Use larger PCB copper area as a heatsink and design a large ground plane beneath the device. For higher power dissipation, an external heatsink or forced-air cooling may be used. Power dissipation is calculated as P = (VIN - VOUT) × IOUT.
