11.3.2 Analog Core Regulator

Figure 11-7. Analog Regulator PSRR vs Frequency and VDD

11.3.3 Inductive Boost Regulator

Unless otherwise specified, operating conditions are: VBAT = 0.5 V–3.6 V, VOUT = 1.8 V–5.0 V, IOUT = 0 mA–50 mA,

LBOOST = 4.7 µH–22 µH, CBOOST = 22 µF || 3 × 1.0 µF || 3 × 0.1 µF, CBAT = 22 µF, IF = 1.0 A. Unless otherwise specified, all charts

and graphs show typical values.
