1 Introduction

Modern low IQ LDOs are designed to minimize power consumption by minimizing the quiescent current consumed, especially under light-load or no-load conditions. This focus on ultra-low IQ enables more efficient power management and simplifies system design for products that are mostly operated in standby or idle state where power consumption must be minimized to maximize battery life (Figure 1).

Texas Instruments (TI) offers a broad range of low IQ LDOs (Table 1) designed for multiple input voltage ranges and output current requirements to accommodate different system needs.
