IXD1701B502MR-G

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

The IXD1701B502MR-G is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Zilog. It provides a stable 5V output with a maximum load current of 150mA. The device supports an input voltage range up to 28V and features a typical dropout voltage of 1.3V at 100mA. Key electrical specifications include a quiescent current of 105µA, a supply current of 125µA, and a power supply rejection ratio (PSRR) of 50dB at 1kHz. It operates within a temperature range of -40°C to 85°C and includes overcurrent, thermal overload, and short-circuit protection.

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

Verify the specific suffix MR-G against official Zilog documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with RoHS3 standards as indicated in compliance records. Confirm availability status directly with authorized distributors, as supply constraints may affect lead times. Validate that the SOT-25 footprint matches your PCB layout requirements before finalizing procurement.

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

Select this component when a fixed 5V output is required with moderate current capability up to 150mA. It is suitable for applications where input voltages do not exceed 28V and low static current consumption is prioritized. Consider the SOT-25 package size for space-constrained designs. Verify that the 1.3V dropout voltage meets the minimum headroom requirements of your specific input-to-output voltage differential.

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

This part belongs to the IXD1701 series of LDO regulators from Zilog, categorized under PMIC linear voltage regulators. It shares the core IXD1701 architecture but is distinguished by its fixed 5V output voltage and specific SOT-25 surface-mount packaging. The series is designed for general-purpose power management tasks requiring stable, regulated DC voltage sources.

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

Cross-reference with other IXD1701 variants offering different output voltages or packages if 5V is not required. Verify functional equivalence with other 150mA LDOs featuring similar PSRR and protection profiles. Ensure any substitute maintains the same enable pin functionality and thermal characteristics.
