DI62063.3S2

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

The DI62063.3S2 is a low dropout fixed positive voltage regulator from the DI6206xxS2 series, manufactured by Diotec Semiconductor. It provides a nominal output voltage of 3.3V with a tolerance of ±2%. The device supports a maximum output current of 200mA and operates within an input voltage range up to 6.0V. Key electrical characteristics include a quiescent current of 8.0µA, line regulation of 0.05%/V typical, and load regulation of 60mV maximum. Dropout voltages are specified at 350mV (typical) for 30mA and 680mV (maximum) for 100mA loads. The component features built-in current limiting and thermal shutdown protection, operating reliably across a junction temperature range of -40°C to +85°C.

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

Verify that the ordered part corresponds specifically to the DI62063.3S2 marking code to ensure the correct 3.3V output voltage variant. Confirm compliance requirements such as RoHS and REACH status if applicable to your manufacturing process. Check the datasheet for specific soldering and assembly conditions, including the 260°C/10s limit. Ensure the design accounts for the commercial grade reliability level and standard application suitability defined in the manufacturer's documentation.

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

Select this regulator when a stable 3.3V rail is required with a maximum load current of 200mA. Consider the input voltage headroom, as the dropout voltage increases significantly at higher currents; ensure VIN remains sufficiently above VOUT to maintain regulation. The low quiescent current makes it suitable for battery-powered applications. Verify that the thermal resistance and PCB copper pad area meet the power dissipation requirements for the expected ambient temperature and load conditions.

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

This component belongs to the DI6206xxS2 series of low dropout fixed positive voltage regulators. The series offers various fixed output voltages including 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, and 3.6V, all sharing similar package and protection features. It is distinct from the DI6206xxS1 series, which offers tighter ±1% voltage tolerance. The S2 version is designed for commercial grade applications and utilizes a SOT-23/TO-236 surface-mount package.

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

For equivalent performance with tighter tolerance, consider the DI62063.3S1 variant from the same manufacturer, which offers ±1% output voltage accuracy. Other members of the DI6206xxS2 series may serve as alternatives if different output voltages are acceptable. Cross-reference with other CMOS LDOs offering similar 200mA current capability and SOT-23 packaging if sourcing constraints require.
