Frequently Asked Questions
How low is the quiescent current of the TC55RP2302ECB and why does that matter for coin-cell designs?
The TC55RP2302ECB draws only 1 µA of quiescent current, making it one of the most power-efficient LDO regulators available. In a coin-cell application with a 220 mAh CR2032 battery and no load, this alone allows over 25 years of standby operation, critical for long-lifetime IoT sensors and memory backup circuits.
What is the output voltage accuracy of the TC55RP2302ECB across its operating range?
The TC55RP2302ECB provides a fixed 2.3 V output with a tolerance range of 2.254 V to 2.346 V, representing ±2% accuracy. This tight regulation is sufficient for powering microcontrollers, sensors, and reference circuits that require stable 2.3 V rails with input voltages up to 10 V.
For a compact wearable PCB, what board area does the SOT-23 package of the TC55RP2302ECB occupy?
The SOT-23 (TO-236) package of the TC55RP2302ECB measures approximately 2.9 mm × 1.6 mm, occupying under 5 mm² of PCB area. Its 3-pin outline requires only two external bypass capacitors, making it one of the smallest LDO regulator solutions for wearable health monitors and compact sensor nodes.
