TS5213CX533 RFG

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

The TS5213CX533 RFG is an 80mA low noise LDO voltage regulator with a fixed 3.3V output, housed in an SOT-25 package. It features ultra-low dropout voltage (typically 50mV at light loads and 320mV at 80mA) and very low ground current (225uA at 20mA). The device includes a precision voltage reference, error correction circuit, current limited output driver, over temperature shutdown, and reverse battery protection. It operates within an input supply voltage range of +2.5V to +16V and supports junction temperatures from -40°C to +125°C.

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

This part belongs to the TS5213 series of 80mA Low Noise LDO Voltage Regulators manufactured by Taiwan Semiconductor. The series offers similar performance characteristics across various fixed output voltages, including 5V variants like the TS5213CX550. All models share the same SOT-25 packaging and feature set, differing primarily in their regulated output voltage levels.

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

Direct substitutes within the same family include other TS5213 variants with different output voltages if the voltage requirement changes. For identical 3.3V output, verify pin compatibility and electrical specifications against other manufacturers' LDOs offering 80mA current capability in SOT-25 packages.

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

What is the minimum output capacitance required for stability?

The TS5213 requires a minimum output capacitance of 0.47μF to maintain stability and improve transient response.

How does the Enable (EN) pin function?

The EN pin is active-high (>2V) and allows ON/OFF control of the regulator. When pulled low (<0.6V), the device shuts down, reducing current drain to micro-amperes.

Is the device stable with no load?

Yes, the TS5213 series remains stable and in regulation even with no load, which is beneficial for CMOS RAM keep-alive applications.
