S-1323B48PF-N9HTFU

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

The S-1323B48PF-N9HTFU is a CMOS voltage regulator from the S-1323 Series by ABLIC Inc. It provides a fixed output voltage of 4.8 V with an accuracy of ±1.0%. The device operates within an input voltage range of 2.0 V to 6.5 V and supports an output current of up to 150 mA when VIN exceeds VOUT(S) + 1.0 V. It features a typical ripple rejection of 70 dB at 1.0 kHz and a dropout voltage of 0.50 V typ. Current consumption is 70 µA during operation and 0.1 µA in power-off mode. The component is housed in an SNT-4A package and functions across an ambient temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Built-in low on-resistance P-channel MOS FET output transistor enables low dropout voltage and high output current capability.
• Integrated overcurrent protection circuit limits output current to prevent damage under overload conditions.
• Dedicated ON/OFF pin allows complete shutdown of internal circuits, significantly reducing current consumption for battery life extension.
• Compatible with small ceramic capacitors (1.0 µF or more) for both input and output stabilization due to low ESR requirements.

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

Verify the specific ordering suffix against the manufacturer's product name structure documentation to confirm package type and environmental compliance. Confirm that the 'NOT RECOMMENDED FOR NEW DESIGN' status does not impact immediate procurement needs. Ensure input and output capacitor selections meet the specified ESR and capacitance values to guarantee stability and prevent oscillation during operation.

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

Select this component when a fixed 4.8 V output is required with high accuracy and low quiescent current. Ensure the application input voltage remains within the 2.0 V to 6.5 V range and accounts for the minimum dropout voltage requirement. Verify that the load current does not exceed 150 mA and that package power dissipation limits are respected under maximum operating temperatures.
