What are the key features of TPS7A7836PWPR?
- Capacitor-drop power path accepts 70 VAC to 270 VAC directly, eliminating a transformer and reducing bill-of-materials cost and PCB area
- 120 mA maximum output current with integrated input fault protection for robust operation in hostile AC-line environments
- 17 V to 23 V DC input range and -40 °C to 125 °C operating temperature for industrial and smart-home appliance applications
- 14-HTSSOP package integrates rectification, regulation, and fault protection into a single compact footprint for space-critical AC-to-DC designs
What is TPS7A7836PWPR used for?
The TPS7A7836PWPR targets smart home appliances, industrial sensors, and IoT gateway modules that require a compact non-isolated 3.3 V or 5 V DC supply directly from the 85 VAC to 265 VAC mains without a transformer. Its integrated cap-drop architecture and fault protection simplify safety compliance for line-powered door locks, thermostats, smoke detectors, and metering nodes where PCB space is severely limited and a full SMPS would be cost-prohibitive.

Frequently Asked Questions
What AC line voltage range does TPS7A7836PWPR support, and can it operate on both 110 VAC and 230 VAC grids?
The TPS7A7836PWPR operates from 70 VAC to 270 VAC, which covers the full global mains voltage range from 110 VAC North American grids to 230 VAC European grids, making it a single-SKU solution for appliances and sensors sold in multiple regions without requiring different transformer windings or supply variants.
How much output current can TPS7A7836PWPR provide, and which low-power IoT loads does that support?
TPS7A7836PWPR delivers up to 120 mA continuous output current, sufficient to power Wi-Fi microcontrollers drawing 80-100 mA during transmission bursts, Zigbee modules, small relay drivers, and 4-20 mA current-loop transmitters while keeping the regulator well within its safe operating area at 125 °C ambient.
Why would an engineer choose a cap-drop LDO like TPS7A7836PWPR over a flyback SMPS for a smart thermostat powered from 230 VAC?
A cap-drop LDO design using TPS7A7836PWPR eliminates the transformer, secondary rectifier, and controller IC of a flyback SMPS, reducing BOM cost by several dollars and cutting PCB footprint by more than 50% for loads below 120 mA, making it the preferred choice for space-constrained smart thermostat enclosures where efficiency is secondary to size and cost.
What does the integrated input fault protection in TPS7A7836PWPR protect against, and why does that matter for industrial sensors rated -40 °C to 125 °C?
The integrated input fault protection in TPS7A7836PWPR guards against transient overvoltages and surge events on the AC mains, which are especially common in industrial environments where motor switching, lightning, and grid disturbances can produce spikes exceeding 1 kV. This protection, combined with the -40 °C to 125 °C operating range, allows the device to survive in harsh factory-floor or outdoor sensor installations without additional external surge suppression components.
