Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The XC6601B13BER-G is a low voltage input CMOS LDO regulator from Torex Semiconductor, housed in an USP-6C package. It provides a fixed output voltage of 1.35V with ±20mV accuracy. The device supports a maximum output current of 400mA and operates within an input voltage range of 1.0V to 3.0V. Key electrical parameters include a typical bias current of 25μA, standby current of 0.1μA, and dropout voltage ranging from 38mV to 179mV depending on load conditions. It features built-in soft-start, thermal shutdown, UVLO, and CL auto-discharge functions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and taping orientation. Ensure the CE pin logic level matches the design requirements, as the B-series lacks an internal pull-down resistor. Confirm compliance with RoHS standards and check for any specific mounting recommendations regarding the heat dissipation pad in the USP-6C package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring low dropout voltage and high efficiency at low output voltages. Consider the USP-6C package for space-constrained designs. Ensure the bias voltage VBIAS is maintained within the specified range relative to the output voltage to guarantee optimal driver transistor performance and stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the XC6601 series of low voltage input LDO regulators. The 'B' designation indicates the absence of an internal pull-down resistor on the CE pin compared to the 'A' series. The 'ER' suffix specifies the USP-6C package configuration, while the 'G' suffix denotes halogen-free and RoHS-compliant manufacturing.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the soft-start function operate?

The soft-start function limits the inrush current from VIN to VOUT during startup, allowing the output voltage to rise gradually. This stabilizes the input voltage source and prevents potential system disturbances.

What is the purpose of the CL auto-discharge feature?

When the CE pin is pulled low, the CL auto-discharge feature activates an internal switch to rapidly discharge the charge stored in the output capacitor (CL). This ensures the output voltage quickly returns to the ground level.
