Linear Regulator for digital island
Overview
Low-leakage LDO in GF 22FDX to supply logic and analog domains (1.8V input supply)
Key Features
- Low dropout: 380mV of dropout at ILOAD= IMAX
- Low Bill-of-Material: optimized in density for the best trade-off for the given output current and input voltage range
- A cost-efficient solution compared to external Power Management
- Behavioral models: ease of integration in SoC and optimization of Power Management Network (PMNet) using models to verify mode transitions as well as noise propagation
- Safe integration in the SoC thanks to transfer functions, templates and profiles included in the specification
