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

Verify the specific ordering suffix '7R-G' corresponds to the USPN-4B02 package type and reel quantity. Confirm that the '-G' designation meets RoHS compliance and halogen-free requirements as specified by the manufacturer. Ensure the selected part number matches the required 1.5V fixed output voltage and Type A configuration before finalizing procurement.

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

Select this component when board space is limited due to its small USPN-4B02 footprint. It is suitable for applications requiring precise voltage regulation under low current loads. Consider the dropout voltage characteristics at varying temperatures if operating near the minimum input voltage threshold. Verify compatibility with ceramic capacitors if an output capacitor is added for transient response improvement.

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

This part belongs to the XC6504 series of low-dropout regulators known for their extremely low power consumption. The series offers various fixed output voltages selectable in 0.1V increments. The Type A variant specifically includes a pull-down resistor on the CE pin and lacks a pull-up resistor, distinguishing it from other configurations within the same family.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult official substitution lists for compatible parts within the XC6504 series or equivalent low-power LDOs from Torex Semiconductor. Ensure any replacement maintains the USPN-4B02 package dimensions and electrical specifications such as 0.6μA standby current and 150mA output capability.

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

How does the XC6504A1517R-G handle output capacitor discharge?

The device features a CL auto-discharge function. When the CE pin is set to a low level, an internal switch connects the VOUT pin to VSS through a discharge resistance (RDCHG), rapidly draining the output capacitor to prevent glitch operations.

What is the output voltage accuracy for this specific model?

Since the output voltage is 1.5V (which is less than 2.0V), the accuracy is specified as ±0.02V. This high precision is achieved through internal laser trimming technology.
