LDO

Low Drop-out Linear Regulators
The PS2292X family of linear regulator provides an easy to use, robust power management solution for a wide variety of applications. The regulators operate with wide input voltage range of 1.7 to 15 Volts while the output voltage is set either internally (0.5 to 5V with 100mV increment) or externally to as low as 0.5V.

Common Features:

• VIN range: 1.7 – 12Volts
• Adjustable and fixed voltage option as low as 0.5V
• Output current ranging from 0.5 to 3A
• Enable pin for LDO on/off
• Bypass pin for low PSRR and output noise
• Optional Power Good with 500µs delay
• Excellent load and line regulation
• Fast transient response

Applications:

• Medical devices
• PC Peripherals
• Instrumentation
• Digital still camera’s
• LCD-TV & Set-top Boxes
• Telecommunication
• Post regulation in switched-mode power
  supplies (SMPS)
• Point-of-load (POL) regulation
• LED lighting
