15.4 LDO3

Unless otherwise noted, the reported measurement were performed at room temperature. External components are those

described in Section 5. “Application Block Diagram” on page 8.

Figure 15-12. LDO3 Transient and Static Load Regulation Performance

LDO3- VIN = 5.5V - VDD3 = 3.3V

Load Step 0 To 200mA / 1us

LDO3 - VIN = 5.5V - VDD3 = 3.3V

Load Step 200 To 0mA / 1us

LDO3 - VIN = 3.6V - VDD3 = 3.3V

Static Load Regulation - 0 To 200mA

LDO3 - VDD3 = 3.3V - 200mA output load

Drop Out Characteristic.

(VDD3
