Low dropout regulators (LDOs) are a simple and cost-effective way to get a regulated output voltage from higher input voltage. LDOs provide great simplicity for the system design as they are widely used in broad applications due to no switching noise and small size.The AP7380 series is a positive voltage regulator IC. The AP7380 has features of wide input voltage range, high accuracy, low dropout voltage, current limit and ultra-low quiescent current which make it ideal for use in various USB and portable devices and instrument application. The IC consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection, and a chip enable circuit. The AP7380 is available in 3.0V, 3.3V, 4.15V, 4.4V and 5.0V fixed output voltage versions.Wide Input Voltage Range: Up to 24V Low Dropout Voltage: VDROP = 580mV @ IOUT = 50mA Low Ground Current High Output Voltage Accuracy Compatible with Low ESR Ceramic Capacitor Excellent Line/Load Regulation Thermal Shutdown Function Applications Battery-powered Equipment Laptop, Palmtops, Notebook Computers Portable Information Appliances More information:  | | Maximum Output Current: | 150mA | Regulator Type: | Low Dropout Voltage | Number of Outputs: | 1 | Output Voltage: | 3.6 V | Line Regulation: | 0.05 %/V | Load Regulation: | 0.5 V | Mounting Type: | Surface Mount | Polarity: | Positive | Package Type: | SOT-89 | Quiescent Current: | 1.8µA | Pin Count: | 3 + Tab | Output Type: | Fixed | Dimensions: | 4.6 x 2.6 x 1.6mm | Height: | 1.6mm | Maximum Input Voltage: | 24 V |
