I am currently designing a circuit where I have typically several IC. I have a LDO (SGM2019-ADJ) which steps 3.8V down to 3.3V with a max output of 250 mA. This 3.3V rail is dedicated to supplying an audio codec (ALC5616) which consumes a max of 4.3 mA @3.3V if I am not mistaken.
I also have the following devices:
- MCU TIVA C TM4C123: max 30mA@3.3V
- GPS module (L70-R): max 100mA@3.3V
- EEPROM (M24M02-DRMN6TP): max 5mA@3.3V
- TF card: max 45mA@3.3V
- RS232: 1mA@3.3V
Can I safely connect all those device on the output of the LDO or should I add a second rail of 3.3V with another LDO in parallel ?
