AP2120 BCDSEMI [BCD Semiconductor Manufacturing Limited], AP2120 Datasheet - Page 19

• Manufacturer Part Number: AP2120
• Description: HIGH SPEED, EXTREMELY LOW NOISE LDO REGULATOR
• Manufacturer: BCDSEMI [BCD Semiconductor Manufacturing Limited]

Note: Filter capacitors are required at the AP2120's input and output. 1µF capacitor is required at the input. The
minimum output capacitance required for stability should be more than 1µF with ESR from 0.01Ω to 100Ω.
Ceramic capacitors are recommended.
