Product Attributes

Features

• High-accuracy CMOS LDO voltage regulator with low quiescent current, high PSRR, and low dropout voltage
• Internally includes voltage reference, error amplifier, pass transistor, current limiter, and phase compensator
• Foldback circuit in current limiter serves as output current limiter and short-circuit protection for output pin
• Fully compatible with low-ESR ceramic capacitors for reduced cost and improved output stability
• Maintains high output stability during frequent load transients with excellent transient response and high PSRR across a wide frequency range
• CE function allows disabling regulator output for significantly reduced power consumption
• Maximum output current: 400mA (VIN = 4.3V, VOUT = 3.3V)
• Dropout voltage: 110mV @ ILOAD = 100mA
• Operating voltage range: 1.8V ~ 5.5V
• Output voltage range: 1.2V ~ 5.0V
• High accuracy: ±1%
