Introduction

The LN1134 series are high-speed, low-dropout, high-accuracy output voltage, low quiescent current positive voltage regulators developed using CMOS technology. Due to the built-in low on-resistance transistor, the dropout voltage is low, enabling large output current capability. To prevent the load current from exceeding the current capacity of the output transistor, overcurrent and other protection circuits are built in.

Features

• Selectable output voltage: 1.0~5.0V range, 0.1V step increments
• High output voltage accuracy: ±2.0%
• Low dropout voltage: 300mV typical (3.0V output product, Iout = 100mA)
• High ripple rejection ratio: 70dB (10kHz)
• Low quiescent current: 70μA typical
• Maximum output current: 300mA (VIN ≥ VOUT + 1V)
• Standby current: less than 2μA
• Built-in protection: overcurrent protection, discharge transistor

Applications

• Mobile phones
• Cordless phones
• Cameras, video recording equipment
• Portable gaming consoles
• Portable AV equipment
• Voltage reference sources for battery-powered systems
