Frequently Asked Questions
How low is the quiescent current of the TPS78227, and why does this matter for coin-cell-powered designs?
The TPS78227 has a quiescent current of just 1 µA, which is critical for coin-cell-powered designs such as glucose monitors and door sensors that spend most of their time in sleep mode. A quiescent current of 1 µA rather than 50 µA or more can extend battery life by months in low-duty-cycle IoT applications.
What is the maximum output current and typical dropout voltage of the TPS78227?
The TPS78227 delivers a maximum output current of 150 mA with a typical dropout voltage of 130 mV at full load. The maximum specified dropout is 250 mV, meaning the input rail need only be 250 mV above the regulated output to maintain regulation, which is advantageous for designs running near the end of a battery discharge cycle.
Which input voltage range does the TPS78227 support, and can it operate from a single-cell lithium battery?
The TPS78227 accepts input voltages from 2.2 V to 5.5 V (absolute max 6 V), making it directly compatible with single-cell lithium-ion batteries that discharge from approximately 4.2 V down to 3.0 V. Designers do not need a boost converter to maintain regulation down to the low end of the battery's discharge curve, provided the output voltage is set at least 130 mV below the battery voltage.
For a compact wearable PCB, how does the TPS78227's package size compare to SOT-23 LDO alternatives?
The TPS78227DRVTG4 is housed in a 6-pin SON (Small Outline No-lead) package with a 1.5 mm x 1.5 mm footprint, which is roughly 50% smaller than a standard SOT-23-5 package measuring approximately 2.9 mm x 1.6 mm. This size advantage is significant for wearable and hearing-aid PCB designs constrained to areas under 10 mm².
How does the TPS78227's line regulation specification affect output accuracy in systems with noisy supply rails?
The TPS78227 achieves a maximum line regulation of 0.027%, meaning its output voltage shifts by less than 0.27 mV per 1 V change on the input rail. This tight regulation ensures that microcontroller ADC reference voltages and precision sensor supplies remain stable even when switching regulators upstream introduce voltage ripple of several hundred millivolts.
