package

Operating temperature range:

-40°C to +105°C

No-load input current as low

The LMTM78_0.5 Series are high eﬃciency switching regulators. The

converters feature high eﬃciency, low loss and short-circuit protection

in a

compact DFN package. These products are widely used in applications

such as industrial control, instrumentation and electric power.

* 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.

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.

Table 1

Note:

1. The required C1 and C2 capacitors must be connected as close as possible

to the terminals of the module;

2. Refer to Table 1 for C1 and C2 capacitor values. For certain applications,

increased values and/or tantalum or low ESR electrolytic capacitors may

also be used instead;

3. Converter cannot be used for hot swap and with output in parallel.
