[38] LOADSW/LDO: LDO startup time exceeds specification

nPM1304 Engineering A Errata

This anomaly applies to Engineering A, build codes CAAA-AA0, QEAA-AA0.

Symptoms

LDO startup duration is significantly longer than the tSS typical value stated in LOADSW/LDO Electrical specification.

Conditions

The LDO is enabled when BUCKs are disabled or BUCKs have no load and there is no active TWI communication.

Consequences

LDO output voltage slowly rises to the configured VOUTLDO.

Workaround

After enabling the LDO, trigger any TWI command.
