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

Verify the specific ordering suffix against the manufacturer's selection guide to confirm package type, auto discharge function status, and taping specifications. Ensure that external ceramic capacitors meet the recommended capacitance values for stable operation. Confirm compliance with RoHS directives and halogen-free requirements as specified in the product documentation before procurement.

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

Select this component when a fixed 2.7 V output is required with high precision. The DFN(PL)1820-6 package offers high-density mounting capabilities. Consider the thermal dissipation limits based on the ambient temperature and board layout. Verify that the input voltage remains within the 1.7 V to 5.25 V range during all operating conditions.

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

This part belongs to the RP102x Series, which includes variants with different packages such as SOT-23-5 and WLCSP-4-P2. The 'K' designation indicates the DFN(PL)1820-6 package, while '271' specifies the 2.7 V output voltage. The 'B' suffix denotes a Chip Enable pin polarity of active high without an auto discharge function at the off state.
