Applications
The TPS7A0218DBVR is optimized for battery-powered IoT sensors, wearables, and low-power wireless modules where standby current must remain below 1 uA. Its 25 nA quiescent current and 200 mA output make it ideal for supplying microcontrollers, Bluetooth Low Energy SoCs, and sensor ICs in always-on monitoring systems. The enable pin allows the host MCU to power-cycle peripheral subsystems, further extending battery runtime in multi-stage power management architectures.

Frequently Asked Questions
How does the 25 nA quiescent current of TPS7A0218DBVR extend battery life in an always-on IoT sensor?
With only 25 nA quiescent current, the TPS7A0218DBVR draws negligible power during standby, adding less than 0.022 mWh per day from a 3.6 V Li-ion cell. For a 1000 mAh battery supporting a device in deep sleep 99% of the time, the regulator contributes less than 0.2% of total battery drain, extending device lifetime by months compared to regulators with 1 uA to 10 uA quiescent current.
What input voltage range does TPS7A0218DBVR accept and which battery types are directly compatible?
The TPS7A0218DBVR accepts input voltages from 2.3 V to 6 V, covering single-cell Li-ion batteries (2.7 V to 4.2 V), lithium primary cells (3.6 V nominal), two-cell NiMH packs (2.4 V), and regulated 3.3 V or 5 V rails. The 6 V absolute maximum input allows use in USB-powered designs operating from a 5 V bus with up to 10% overvoltage tolerance.
How low is the dropout voltage of TPS7A0218DBVR and what minimum input voltage sustains 1.8 V output at 200 mA?
The TPS7A0218DBVR has a typical dropout voltage of 205 mV at 200 mA load current, meaning the minimum input voltage needed to maintain a 1.8 V regulated output is approximately 2.0 V. This low dropout characteristic allows the device to continue regulating until a Li-ion cell discharges to near its cut-off voltage of 2.5 V to 2.7 V, maximizing usable battery capacity in portable applications.
When should TPS7A0218DBVR be chosen over a switching regulator for powering a BLE SoC at 1.8 V?
TPS7A0218DBVR is preferred over a switching regulator when the input voltage is within 500 mV of the 1.8 V output, peak current does not exceed 200 mA, and switching noise immunity is critical. BLE 2.4 GHz RF front ends benefit from an LDO where a buck converter switching at 1 MHz to 3 MHz would degrade receiver sensitivity by 3 dB to 10 dB. The SOT-23-5 LDO also costs less and simplifies EMC compliance.
