Frequently Asked Questions
How low is the dropout voltage of the TPS79418DGNR, and why does it matter for battery-powered designs?
The TPS79418DGNR has a typical dropout voltage of 0.9 V, allowing it to continue regulating a 1.8 V output from an input as low as 2.7 V. This maximizes usable battery capacity in portable devices where the supply voltage drops toward end-of-discharge.
What output current and voltage accuracy does the TPS79418DGNR provide?
This LDO delivers up to 250 mA with a fixed 1.8 V output, a maximum line regulation of 0.006%, and a maximum load regulation of 0.01%, ensuring the voltage rail stays stable across varying load currents and supply fluctuations in sensitive analog or MCU circuits.
Which applications and board form factors are best matched to the TPS79418DGNR?
IoT sensor nodes, wearable electronics, and wireless modules benefit from this regulator's 2.7 V to 5.5 V input range and 250 mA output. The 8-pin MSOP package (S-PDSO-G8) occupies minimal PCB area, suiting compact multi-rail boards with tight layout constraints.
Does the TPS79418DGNR support power sequencing between voltage rails?
Yes, the device includes a dedicated enable pin that allows the 1.8 V output to be turned on or off independently, enabling controlled power-up and power-down sequencing across multiple rails in FPGA, microcontroller, and RF transceiver system designs.
