* The positive output ctrl pin voltage is referenced to input GND; Negative output

ctrl pin voltage is referenced to -Vo.

* The static level of the Ctrl & Trim pin is 2KV when they are not connected to

external devices; It is suggested to connect an external capacitor (105K/50V)

from Ctrl to GND/-Vo to meet ESD ( 6KV) of the Ctrl pin, and to connect a

varistor (22V/30A) from Trim to GND/-Vo to meet ESD( 6KV) of the Trim pin.

Example:

LMTM78_05-0.5

LM = Series; T = SMT case; M = Micro size; yy = 5Vout; pp = 0.5A

Note:

1. All speciﬁcations measured at Ta = 25°C, humidity <75%, nominal input voltage

and rated output load unless otherwise speciﬁed.

2. In this datasheet, all the test methods of indications are based on corporate

standards.
