+In a low-power compartment, a rear switch limits the output to 1 A (indicated by front-panel "NON FLOATING / 1 A LIMIT" LED).
-* Output voltage: 3.0V to 5.5V DC, floating
-* Output current when plugged into a high power TM500 compartment: 4A

-* Output current when plugged into a regular power TM500 compartment: 1A
+{{Spec | Output voltage | 3.0 V to 5.5 V DC, floating (only if operated in a high-power compartment) }}
+{{Spec | Output current | 4 A (must be limited to 1 A in a low-power compartment); foldback limit from 4.1 A to 1.5 A (latching) }}
+{{Spec | Overvoltage protection | 7 V }}
+{{Spec | Line regulation | ±10 mV for 10% line voltage change }}
+{{Spec | Load regulation | ±5 mV for 0.5 to 4 A load current change, 20 μs transient recovery }}
+{{Spec | Stability and drift | 0.1% + 5 mV drift in 8 hours; max. 0.01%/°C }}
+{{EndSpecs}}
+The regulator circuit uses one 741 and one 5558 opamp.  Reference is a 9 V zener.
