Attempting to use 103fa-5, DDPAK5 version.
Pin 1 - 9VDC battery input. 9.8 VDC measured at pin 1
Pin 2 - 3VDC battery. 2.8VDC measured at pin 2. Appears enable pin works as I can remove this voltage and out is 0 VDC
Pin 3 - GND
Pin 4 not used
No loads …
Hello-
During recent high temperature testing, it was observed that the REG103GA-A with 3.3V in and 3.0V out, the output voltage jumped to 3.3V at 100 degrees C. The same thing happens to the part with 6V in and 5V out - the output jumps to the input voltage…
Other Parts Discussed in Thread: TPS74401 , REG103 Hi All,
We have implemented a DC PCB using REG103-A regulators. Everything is going fine, except for the output of the REG-103A, which is 3.7V instead of the 5.3V we are expecting according to adjustable…

Hello,
I'm
troubleshooting a circuit where a REG103UA-3.3 (a fixed voltage 3.3 VDC
regulator) is being damaged. When the REG103 fails, Vin becomes shorted
(<100 ohms) to Vout and battery voltage carried…
I am curious about the REG103UA-A and its ERROR Flag pin. The datasheet states that it falls low when the expected output voltage is "approximately" 10% (above or below) out of tolerance. However, the datasheet does not state any electrical…
Hi Anthony,
1. The DCR021205 has a current limit threshold of 700 mA (typ). The current limit protection is internal to the LDO (REG103). When the overcurrent condition is removed, the device will restart.
2. The device does have OCP which will reduce…
Other Parts Discussed in Thread: REG103 Hello,
I was looking for the thermal resistance values from junction-to-case for the following three parts:
UCC284DP-5 REG103GA-5 REG103-3.3
Please let me know if this informaiton is available. Thank you.
Regards…
Other Parts Discussed in Thread: REG103 , LP2989 Hi
I want to choose LDO.
Vin=12V Vout=5V
We often use in light load and concern accurary.
Can I use REG103 or which one is better?
Thank you.
