TLV75518PDRVR 1GXH 1.8V LDO

Avalon A1246 hash board 1.8V LDO repair

The TLV75518PDRVR is an ultra-small, low quiescent current, low dropout regulator (LDO) on the Avalon 1246 hash board that delivers 500mA with good line and load transient performance. The chip marked 1GXH, the device provides a fixed output voltage of 1.8V to support the lower core voltages of modern microcontrollers (MCUs). In addition, the TLV75518PDRVR has a low IQ and an enable function to minimize standby power consumption. The device features an internal soft-start feature that reduces inrush current, providing a controlled voltage to the load and minimizing input voltage drop during startup.

Features:

• SOT-23-5 package with 60.3°C/W RθJA available

• Input voltage range: 1.45V to 5.5V

• Low IQ: 25μA (typ)

• Low dropout:

– 238mV (max) at 500mA (3.3VOUT)

• Output accuracy: 1% (maximum at 85°C)

• Built-in soft-start with monotonic VOUT rise

• Foldback current limit

• Active output discharge

• High PSRR: 46dB at 100kHz

• Use 1µF ceramic output capacitor for stability

Application:

• Set-top boxes, TVs and game consoles

• Portable and battery-powered equipment

• Desktops, laptops, and ultrabooks

• Tablet and remote control

• Grid infrastructure and protective relays

• Camera modules and image sensors
