LT7915CT/NOPB – TEXAS INSTRUMENTS

The LT7915CT/NOPB is a low-dropout (LDO) negative voltage regulator from Analog Devices, packaged in a space-saving 6-lead TSOT23 package. It’s specifically designed for applications requiring a stable negative voltage rail with minimal voltage drop, even under high load currents. The device boasts a guaranteed output voltage of -1.235V, with a typical input voltage range of -2.5V to -5.5V. Output current capability reaches a robust 150mA. The LT7915CT/NOPB utilizes a unique architecture minimizing quiescent current to a mere 120µA, ideal for battery-powered applications where efficiency is paramount. Its internal thermal shutdown and short-circuit protection features enhance robustness. The “NOPB” suffix indicates a lead-free, RoHS-compliant package._x000D_

Common use cases include providing a negative supply voltage for operational amplifiers, instrumentation circuits, and precision analog-to-digital converters (ADCs) requiring a stable negative reference. Its low dropout voltage allows for efficient operation with minimal power dissipation, even when the input voltage is only slightly higher than the output voltage. The LT7915CT/NOPB’s advantages lie in its combination of high current capability, low quiescent current, compact packaging, and robust protection features, making it a strong choice for space-constrained, power-sensitive designs requiring a precise negative voltage rail.
