2.8V to 5.5V, 300mA step-down/step-up negative output regulator
LMR70503 is a step-down to step-up converter with adjustable negative output voltage, packaged in a miniature 8-point thin DSBGA package. Its unique control method aims to provide fast transient response, low output noise, high efficiency, and strict regulation in the smallest possible PCB area. LMR70503 has built-in soft start, peak current limitation, minimum switching frequency, and undervoltage lockout (UVLO), without the need for external compensation.
