Key Features
- Dual independent LDO outputs (500 mA + 250 mA) enabling simultaneous regulation of two supply rails from a single IC
- Low dropout voltage of 170 mV nominal (275 mV max) for efficient operation close to the output voltage level
- Fixed output configuration with 4.3 V to 6 V input range covering standard 5 V bus applications with up to 7 V absolute maximum
- RoHS-compliant 20-pin HTSSOP (R-PDSO-G20) package enabling compact, thermally efficient PCB placement
Applications
The TPS70158PWP is designed for dual-rail power supply designs in embedded systems, consumer electronics, and telecommunications equipment where two stable regulated voltages are required from a single 5 V bus. Its low dropout performance makes it ideal for battery-powered portable devices and DSP/FPGA core-plus-I/O supply architectures. Industrial instrumentation and communication modules also benefit from its compact HTSSOP footprint and independent 500 mA and 250 mA output channels.

Frequently Asked Questions
What are the output current ratings of the TPS70158PWP?
The TPS70158PWP provides two regulated outputs: one rated at 500 mA and one at 250 mA. Both outputs are positive, fixed-voltage LDO regulators housed in a single 20-pin HTSSOP package, allowing dual-rail power delivery from one component.
What is the input voltage range and maximum rating for the TPS70158PWP?
The TPS70158PWP operates from an input voltage range of 4.3 V minimum to 6 V maximum, with an absolute maximum input voltage of 7 V. This range is well suited for 5 V system buses with tolerance headroom in USB or regulated adapter-supplied designs.
How low is the dropout voltage of the TPS70158PWP?
The TPS70158PWP has a nominal dropout voltage of 170 mV and a maximum dropout voltage of 275 mV. This low dropout characteristic allows the output voltage to be maintained even when the input voltage is only slightly above the output, improving efficiency in near-rail applications.
What package does the TPS70158PWP use and is it RoHS compliant?
The TPS70158PWP comes in a 20-pin HTSSOP (JESD-30 code R-PDSO-G20) surface-mount package, which features an exposed thermal pad for improved heat dissipation. The Pb-free code is Yes, confirming full RoHS compliance for lead-free production environments.
