What are the key features of TPS781330220DDCTG4?

  • Dual fixed output voltages of 2.2V and 3.3V in a single 5-pin TSOT-23 package, eliminating the need for two discrete LDOs and reducing PCB area
  • Ultra-low 200mV typical dropout voltage at 150mA enables operation from low-voltage inputs as low as 2.2V, extending battery life in portable applications
  • Excellent line regulation of 0.033% maximum ensures stable output voltage over the full 2.2V to 5.5V input range, critical for noise-sensitive analog and RF circuits
  • JESD-609 e4 RoHS-compliant lead-free construction in compact TSOT-23 package ideal for space-constrained wearable and IoT designs

What is TPS781330220DDCTG4 used for?

The TPS781330220DDCTG4 is designed for portable consumer electronics, wearables, and IoT sensor nodes that require two independent stable supply rails from a single compact regulator. Its low dropout and dual-output capability make it ideal for powering a microcontroller core at 2.2V and I/O interfaces at 3.3V simultaneously. The device is also suitable for USB-powered accessories and wireless communication modules needing clean, regulated supplies with minimal external components.

Frequently Asked Questions

What are the two output voltages of the TPS781330220DDCTG4?

The TPS781330220DDCTG4 provides two fixed output voltages: 2.2V and 3.3V, both derived from a single IC in a 5-pin TSOT-23 package. Each output can supply up to 150mA of continuous current, making it suitable for powering a processor core rail and an I/O rail from one device.

What is the dropout voltage of the TPS781330220DDCTG4?

The TPS781330220DDCTG4 has a typical dropout voltage of 200mV and a maximum of 250mV at the full 150mA load. This low dropout means the device can maintain regulation with as little as 2.2V at the input, enabling efficient use of Li-ion and other low-voltage battery sources.

What package does the TPS781330220DDCTG4 use?

The TPS781330220DDCTG4 is housed in a 5-pin TSOT-23 (JESD-30 code R-PDSO-G5) surface-mount package. The TSOT-23 package measures approximately 2.9mm x 1.6mm, making it one of the smallest available for dual-output LDOs and well-suited for space-constrained PCB layouts in wearables and portable devices.

Is the TPS781330220DDCTG4 RoHS compliant?

Yes, the TPS781330220DDCTG4 carries a JESD-609 Code of e4, confirming full RoHS compliance and lead-free construction. The 'G4' suffix in the part number also denotes green/halogen-free packaging, meeting global environmental regulations for electronic components.

What is the input voltage range and what sources can power the TPS781330220DDCTG4?

The TPS781330220DDCTG4 operates with an input voltage from 2.2V minimum to 5.5V maximum, with an absolute maximum rating of 6V. Compatible power sources include single-cell Li-ion batteries (3.6V–4.2V), two-cell NiMH packs, and 5V USB VBUS rails, making it versatile for a wide range of portable and USB-powered designs.
